FAQ
How does sales tax work in the US?
Sales tax is added to the price of goods at checkout and varies by state and locality. For example: California 7.25%, New York ~8%, Texas 8.25%, Florida 6%. Some states have no statewide sales tax.
How do I add sales tax to a price?
Multiply the pre-tax price by the tax rate to get the tax amount, then add it to the price. Example: $1,000 × 7.25% = $72.50 tax, for a $1,072.50 total.
How do I extract tax from a tax-inclusive total?
Divide the total by (1 + rate). Example: a $1,072.50 total at 7.25% gives a $1,000 pre-tax price, so the tax was $72.50. Use the “tax included” toggle to do this automatically.
